Be it known that we, FRANK J. KROMEN- axini and GRANT M. KROMENAKER, both citizens of the United States, and residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Roofing, of which the following is a specification.

Thisinvention relates to 'da roon composed of interlocking shingles, and is particularly concerned with the construction of the individual shingles by which they may be economically produced and 'be effectively combinedto provideI a rain-proof roofing.

An exemplification of this invention is shown in the accompanying drawings wherein- Figure 1 is a plan view of asection of roofing composed of a number of the pres- \ent. shingles Figs. 2 and 3 are transverse and longitudina'l sections therethrough taken respectively on lines 2 2 and 3--3 of Fig. `1;

Fig. 4 is a fra entaryviewin planofv a sheet from whic the shingles are cut; and

Fig. 5 is a plan view of one of the shingles per se.

'I h shin le unit shown in Fig. 5 is formed wit op osite ends each ofthree sections 5, 6', an 7 the first and last bein right angularly related tothe upper and lower edges 8 and 9 respectivel The intermediate end sections 6 are o li uely inclined at angles of about 135 'to t e adjacent sections 5 and 7, bein disposed in substantially right angular re ation to each other. From this construction it follows that the oblique sections 6 diverge in an upward direction, and that the. dimension ofthe upper edge 8 is considerably greater than that of the lower edge 9. Additionally,

` in the body of the shingle are formed two cuts or slits 10 each aligned with an oblique section 6 and proceeding inwardly. therefrom for a .distance whichis: perhaps half way' toward the lower edge 9.

Shingles of the form described ma be produced without waste of material rom a .standard sheet of roofing, such, for instance, as is shown in F1g..4, wherein appears thatthe width ofsuch a sheet may be approximately twice the vertical dimension of a single shingle. The relationship of the several shingles prior to their bein cut from the sheet may best be understo by referring to the markings in Fig. 4

courses are brought Ointo alignment.

'which define shingles designated as A, B,

C, -D, E 'and F. The shingles A, B and C lie in one course to one side of a center line 11 which runs lonvitudiiiall of the sheet, while the shingles l5, E and are arranged in another course that lies to the opposite side thereof. The several shingles in each v course` are alternatel inverted throughout the length iof the s eet, being contiguous to eachother along the lines 5, 6, and 7; these are also the lines of severance, becomin subsequently the end sections 5, 6 an 7 shown in Fig. 5. The shingles so-marked in one course preferably lie opposite other shingles in inverted relation in the'adjacent course, and from this arrangement, itresults that the end sections '5 of two adjacent shingles in opproslite ns is the preferred relationship, as thereby the operation of' severance is facilitated.

In utilizing shingles of such a construction to provide a water-tight roofing, we lcombine .the'same as follows'. Upon a roof,

usually slanted, the shingles are arrangedin horizontal rows, as indicated in Fig. l, with the end sections 5 in abutting relation. The top row comprises shingles designated as a, b, and c, the next lower row includes other shingles d and e, whilein the row next in order are-shingles f, g and h. These rows are in practice first formed at the lower edge of the roof, but for convenience in description, we will consider mainly those along its upper edge. Below the topmost shingle row, 'each succeeding row is lower by a distance about equal to the length of the end sections 5 or 7, these being of the same dimension. In the second row, however, the shingles are staggered with respect to those in the 'top row in that the abutting edges of the second row shingles lie about midwayr of the horizontal length of those in the'top row. The shingles in the third row align with those in the top row and hence are staggered with respect to those in the secondrow, and this stag gered arran ement is followed through to the bottom s ingle row.

It will be ap arent that each row of shingles laps part over the' next lower row and also the row t erebelow. as indicated in Fig. 2. Portions of each shingle so overlapped do, however, overlap the adjacent lower corners of the proximate shingles in the next higher row. This is accomplished vin Fig. 1.

The roofing formed by our invention presents` an appearance that is both attractive and unusual. .The portion of each shingle exposed to view -is bordered by straight lines at top and bottom, and at each end by threepart zigzao` lines which coincide with the zigzag borders of the adjacent shingles. The exact dimensions and angular relationship of the shingle edges are, of course, variable within certain li1nits,'but those suggested in the drawings are well suited to the purposes of this invention for which protection is hereby sought in claims as follows t' We claim:

1. As a new article of manufacture, a roofing shingle having a lower edge, ends which extend upwardly in right angular relation thereto, thence outwardly in div-'erg-l ing relation, and thence upwardly again in parallelism with the first mentioned sections thereof,.and a top edge parallel to the lower edge, there being slits extending into the body of the shingle in line with the outwardly extended end sections, substantially as described.

2; As a new article of manufacture, a roofing shingle having diverging edges in substantially right angular relation with each other, there being parallel continua.- tions at each extremity thereof forming an angle of approximately 135 therewith, and upper and lower edges in parallelism, there being slits extending into the shingle body in line with the diverging edges, substantially as described.

3. A roofing comprising, in combination, a plurality of shingles each having upper and lower edges of unequal length, ends conf sisting of two -parallel sections and an inter- `mediate oblique section which is angularly related to the other corresponding section, the several shingles so formed being arranged in rows with one parallel end of each in abutting relation to the corresponding end of the other, and each succeeding lower row of shingles occupying a staggered endwise relation to the one above, each row of shingles being overlapped in part by the row4 above, there being slits in alignment with the oblique ends of each shingle extending I 4. A roofing comprising, in'combination,

a plurality of shingles each having upper and lower edges in parallelism and -ends therebetween which provide three sections the intermediate ones of which vare obliquely related to each other at an angle of about the several shingles so formed being arranged in a row with one of their end sections in abutting relation with a corresponding section of the other, other rows of shingles similarly arranged and each 'disposed parallel to the first row and each arranged to partially overlap the onev therebelow, there being slits formed in each shingle through which a portion 4of theoverlapped shingle may exten-d to lie upon the outer side thereof, substantially as described'.

A`rooling comprising, in combination, a plurality of shingles, all alike, and `each slitted to interlock with those adjacent by lapping a portion of itself therebelow and a portion thereabove, the several shingles being. formed with parallel upper and lower edges of unequal length and with side edges having three sectionsv thel end ones of'whiohl 'voyl are in right angular relation to the upper and lower shingle edges, the middle sections being obliquely related thereto, the assem.

bly of shingles so formed providin a roof.- ing with exposed shingle surfaces ordered by upper and lower edges in parallelism and zigzag ends in three sections one of which is cro-incident with the corresponding sections of the proximate shingles, substantially as described.

6. A roofing comprising, in combina-tion, a plurality of shingles, all alike, and each slitted to interlock with those adjacent by lapping a portion of itself therebelow and a portion thereabove, the severalv shingles being formed with parallel upper and lower edges of unequal length and with side edges having three sections the end ones of .which are in right angular relation tothe upper and lower shingle edges, the middle sections being obliquely related thereto, the assembly of shingles so `forme-d providing a 'roofing with exposed shingle surfaceswhich have two opposite edges in parallelism and the remaining edges of zigzag formation, substantially as described.
